This tool provides a reliable initial assessment based on real data from our 52 coverage areas across London. We use actual project data, local planning constraints, and current 2025 pricing to generate your report. However, every property is unique — for a precise assessment, we recommend booking a free site visit where our architects can evaluate your specific property in person.
It depends on the scope of work. Many internal renovations like kitchen and bathroom refurbishments typically fall under permitted development rights. However, extensions, loft conversions, and basement conversions usually require planning permission, especially in conservation areas where Article 4 directions may remove permitted development rights. Our team handles the entire planning process with a 97% approval rate across London boroughs.
London renovation costs vary significantly by area, property type, and specification level. As a guide: kitchen renovations start from around £800/sqm, bathroom renovations from £1,000/sqm, loft conversions from £1,800/sqm, house extensions from £2,200/sqm, and basement conversions from £2,800/sqm. Prime areas like Mayfair, Chelsea, and Knightsbridge carry a 20-25% premium. Use our detailed cost calculator for a personalised estimate.
Conservation areas protect the character and appearance of historically significant neighbourhoods. Restrictions typically include controls on external alterations, materials, demolition, and tree works. Article 4 directions can remove permitted development rights entirely, meaning you need planning permission even for changes that would normally be allowed. Our heritage team specialises in designing schemes that respect conservation area character while achieving your renovation goals.
Yes, listed buildings can absolutely be renovated — but you'll need Listed Building Consent for any works that affect the building's character or special interest, including internal alterations. This is in addition to any planning permission required. Our RIBA-chartered architects have extensive experience with Grade I and Grade II listed properties, and we maintain strong relationships with heritage officers across London boroughs to ensure smooth approvals.
Timelines depend on project scope and complexity. A kitchen renovation typically takes 6-10 weeks, a bathroom 4-6 weeks, a loft conversion 10-14 weeks, an extension 12-20 weeks, and a full refurbishment 16-30 weeks. Basement conversions are the most involved at 6-12 months. Planning permission adds 8-12 weeks for standard householder applications. We provide a detailed programme at the outset so you know exactly what to expect.
